A Penknife in My Heart

A Penknife in My Heart is a 1958 crime thriller by Cecil Day-Lewis, published under his pen name Nicholas Blake. The novel stands apart from his Nigel Strangeways detective series as a standalone work. Two strangers cross paths and discover they share a deadly wish - each wants someone eliminated but fears detection. They devise a scheme to exchange murders, providing each other with foolproof alibis. The novel bears similarities to Patricia Highsmith's Strangers on a Train, though Day-Lewis stated he had no prior knowledge of that work. Set in London, the story follows these two men as they navigate the consequences of their fatal arrangement. The novel examines themes of moral responsibility and psychological manipulation, asking whether outsourcing a crime makes one less culpable for its execution. Through its tight plot structure, it raises questions about the nature of guilt and complicity.
